6. One paragraph description of your model (e.g. abstract from report or
   paper);

     This model is a system of coupled sub-models which simulate the time
evolution of 3-dimensional snow-depth distributions.  The blowing and
drifting snow submodel includes an accounting of the relevant snow
transport mechanisms, such as saltation and turbulent suspension,
surface shear stress modifications in the presence of saltation,
sublimation of the blowing and drifting snow, wind field adjustments
for topography, and snow-vegetation interactions are included through
a vegetation snow-holding capacity.  When driven with observed or modeled
atmospheric forcing, this submodel describes how the winter snow cover 
accumulates and is redistributed by the interactions of wind and 
topography.  In addition, it provides an accounting of the snow-pack 
losses due to the sublimation of the wind-transported snow.  The
energy-balance melt submodel is available to simulate snow-melt related
processes.  Variations of the modeling system are being incorporated 
into the Regional Atmospheric Modeling System (RAMS) for weather and 
climate simulation purposes.
